Application filed July 3, 1920. Serial No..393,880.

T0 all whom it may concer/n Be it known that l, FREDERICK ZIRKULY, residing at the city of New York, borough of Brooklyn, Kings County, in the State of New York, have invented certain new and useful Improvements in Refrigerators, of which the following is a full, clear, and exact specification.

My invention relates to improvements in refrigerating apparatus, and the same has for its object more particularly to provide a simple, eicient and reliable apparatus by means of which the refrigerating rlrnedium may be' protected against undue oss.

Further said invention has for its object to provide an apparatus in which the refrigerating medium is utilized to provide a source of cold air; which serves' yto surround or envelope the compartment containing said refrigerating vmedium as well as the compartments containing the articles of food or other substances to be preserved.

Further said invention has for its object to provide an apparatus having means tor controlling the passage of cold air issuing from the refrigerating compartment and passing into and through the air space surrounding or enveloping said refrigerating compartment, and the other compartments communicating therewith.

Further said invention has for its object to provide an apparatus in which the several compartments may be severally automatically closed against each other or against the refrigerating compartment in order to prevent the loss of cold air therefrom when the doors of said compartments are opened.

Other objects will in part be obvious, and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, my invention consists in the novel details of construction, and in the combination, connection and arrangement of p parts hereinafter more fully described and then pointed out in the claims.

Figure 1 is a front elevation, partly broken away, showing one form of refrigerator constructed according to, and embodying said invention;

Fig. 2 is a vertical 2-2 of Figure 3;

section on the line Fig. 3 is a vertical section on the line 3 3 of Figure 1;

Fig. 4 is a horizontal section taken essentially on the line 4.-4 of Figure 2: and

Fig. 5 is a detail sectional view showing the construction of the refrigerator caslng. l

In said drawings 10 designates a refrigerator comprising an outer casing 11 made of wood or other suitable material, and lined upon its inner side with a plurality of sheets of'oil paper or the like, 12; a layer of wood 13, and an inner covering comprising a plurality of sheets of oil paper or the like, 14.

Within the outer casing 10 is disposed a sm ller inner casing 15 of wood which is maintained in properly spaced relation to said outer casing by stays 16, so as to form an air space 17 between the top, bottom, sides and back of said inner and outer casings. The inner casing 15 is provided upon its outer side with a plurality of layers of oil paper or the like 18, and upon itsA inner side with the usual metal lining 19. i

The interior of the inner casing 15 is divided into 'three compartments 20, 21, and 22, by shelves 20a, 21B. The compartment 20 is adapted to receive a refrigerating medium such as ice, or other suitable refrig.

erating medium.

Within the refrigerating compartment 20 is provided an ice-tray '23 having a trough 23a disposed below the same and connected with a drain pipe 24 having a trap 25 at its lower end without the boX `forming a water seal to prevent the entrance of warm air into the interior of the refrigerator.

rThe shelves 20, 21"L are each provided with a series of openings or slots 26, adapted to register with corresponding openings or slots 27 provided in plates 28, 29, arranged below said shelves 20a, 21, respectively, and slidably supported in guides 30.

Upon oneside wall of the inner casing 15, below the shelves 20a, 21a, are secured bearings or brackets 31, 32, respectively. Upon the upper bearings or brackets 31 is mounted connected to the under side lower bearing or bracket 32. 32EL denotes va shaft mounted in the lower bearings or brackets 32 upon which is fixed a bell-crank lever 36 having one end pivotally secured to lsaid link 34 and its other end pivotally connected to the under side of the lower sliding plate 29.

37, 38 denote latches of the two lower compartment doors 39, 40, respectively, which latches are fixed to the shafts 37, 38a, respectively. rll`he disk 35 is fixed upon the shaft 38a, and an arm 37b is fixed to the shaft 37a, so that when either of the latches is raised to permit of the opening of its door, the bell-crank levers 33, 36 will be simultaneously actuated to cause the sliding plates 28, 29 to be moved and close the openings or slots in the shelves 20E, 21a.

To aid in shifting the sliding plates 28.1 29, and maintaining the openings 26, 27 thereof out of register when the doors, or either of them, are opened, springs 41 are provided. One end of each spring 4is secured'to the inner side of the inner casing 15, and the other end secured to each of the sliding plates 28, 29.

ln order to permit the cold air from the refrigerating compartment 20 to pass into the air spaces 17, the side wall of the inner casing 15, adjacent to the lower portions ot the compartments' 20, 21 and 22, is provided with separate series of openings or slots 42, and upon the outer side of said side wall of the inner casing 15 is provided a sliding plate 43 provided with openings or slots 44 corresponding with the openings or slots 42 in said side wall. The sliding plate 43 has its upper end, which extends through the top of the outer casing 10, provided with a handle portion or head 45. 46 denotes guides secured to the outer side of the inner casing 15 within which the sliding plate 43 works. n

rllhe outer easing 10 is provided at its top with yan opening or vent 47 which is normally sealed by a screw plug 47 a.

48 denotes a coil of pipe disposed within the refrigerating compartment 20 to provide a supply of cold water or other fluid. 49 denotes the inlet, and 50 the outlet for said coil.

rllhe operation of the apparatus is as :tollows:

lce is first placed into the refri erating compartment 20 and thereupon all te doors of the refrigerator closed. Thereupon the sliding plate 43 is lowered by means of the handle or head 45, and the openings 44 brought into register with the openings 42 in the wall of the inner casing 15, at

each of the compartments 20, 21, 22. At the same time the vent 47 in the top of the outer casing 10 is opened by removing the plug 47a. The sliding plate 43 and the vent 47 are permitted to remain open a sucient length incasso of time to permit cold air to pass from the refrigerating compartment 20 into, and completely displace the warmer air occupying the space 17 between the outer casing 10 and the inner casing 15. When said space is completely filled with cold air the slide 43 is moved upward and the openings 44 therein brought into register with the openings 42 in the side wall of the inner casing 15, and the plug 478b again secured in the vent 47. The inner casing 15 will thereupon be substantially enclosed by an envelope of cold. air.

When either of the doors 39, 40 of the lower compartments 21, 22 is opened the slides 28, 29 will be actuated to close the openings 26 in said shelves, and thus prevent the passage of cold air from any one of said compartments to the other thereof.

lt will be noted that by means of my improved construction the refrigerating me dium, as well as the air cooled thereby, will be conserved to the greatest extent possible, and at the same time cold air will only be lost or impaired in the particular compartments to which the access is had for the time being.
